Fixed the 32, 16, and 8 bit pseudo regs for x86_64 (real reg of "rax" which subvalues "eax", "ax", etc...) to correctly get updated when stepping. Also fixed it so actual registers can specify what other registers must be invalidated when a register is modified. Previously, only pseudo registers could invalidate other registers.

Modified the LLDB qRegisterInfo extension to the GDB remote interface to support specifying the containing registers with the new "container-regs" key whose value is a comma separated list of register numbers. Also added a "invalidate-regs" key whose value is also a comma separated list of register numbers. 

Removed the hack GDBRemoteDynamicRegisterInfo::Addx86_64ConvenienceRegisters() function and modified "debugserver" to specify the registers correctly using the new "container-regs" and "invalidate-regs" keys.

This is more code to isolate the use of the Attribute class to that of just
holding one attribute instead of a collection of attributes.

Providing a special mode of operator for "memory read -f c-str" which actually works in most common cases
Where the old behavior would provide:
(lldb) mem read --format s `foo`
0x100000f5d: NULL

Now we do:
(lldb) mem read --format s `foo`
0x100000f5d: "hello world"

You can also specify a count and that many strings will be showed starting at the initial address:
(lldb) mem read -c 2 -f c-str `foo`
0x100000f1d: "hello world"
0x100000f29: "short"

Very similar to what we do for record definitions:
- tighten down what is an enum definition, so that we don't mistake a
  function for an enum
- allow common idioms around declarations (we'll want to handle that
  more centrally in the future)

We now correctly format:
enum X f() {
  a();
  return 42;
}

modules test case.

rework the Bitstream reader to actually work a machine word at a time, instead of 32-bits at a time.
This cuts in half the number of virtual methods called to refill that word when compiling on a 64-bit
host, and will make 64-bit read operations faster.

A SparseMultiSet adds multiset behavior to SparseSet, while retaining SparseSet's desirable properties. Essentially, SparseMultiSet provides multiset behavior by storing its dense data in doubly linked lists that are inlined into the dense vector. This allows it to provide good data locality as well as vector-like constant-time clear() and fast constant time find(), insert(), and erase(). It also allows SparseMultiSet to have a builtin recycler rather than keeping SparseSet's behavior of always swapping upon removal, which allows it to preserve more iterators. It's often a better alternative to a SparseSet of a growable container or vector-of-vector.

We now only put empty blocks into a single line, if all of:
- all tokens of the structural element fit into a single line
- we're not in a control flow statement

Note that we usually don't put record definitions into a single line, as
there's usually at least one more token (the semicolon) after the
closing brace. This doesn't hold when we are in a context where there is
no semicolon, like "enum E {}".

There were some missing tests around joining lines around the corner
cases of the allowed number of columns, so this patch adds some.
